Redstone Fin Can Revision 3

Posted In Mercury Redstone 1:52 Scale, US Army Redstone 1:52 Scale

I revised the fin can adding in some detail at the bottom of the fins, and added the wedge shaped coupling connectors.

US Army Redstone Part 2

Posted In US Army Redstone 1:52 Scale

I figured out the problem with the nose cone. It was a two part issue, while some of the polygons appear to be properly touching in Tinkercad, they really were not, there was a tiny gap. The second issue was a mistake I made in Tinkercad for the wall thickness, Continue Reading

US Army Redstone Part 1

Posted In US Army Redstone 1:52 Scale

While I was searching for the Mercury Redstone scale date, I was reminded of the US Army Redstone Missile. I used the scale data I came across and created a 3D model of a nose cone in the same 1:52 scale for an ST-16/BT-56 tube size. I printed a test Continue Reading

Mercury Redstone 1:52 Part 4

Posted on May 26, 2019June 2, 2019 by Rocketeer
Posted In Mercury Redstone 1:52 Scale

I decided to try my hand at making a 3D part and created a fin can for it. I didn’t do a lot of detail, did about what I would have done in balsa. And it certainly isn’t scale, but it turned out pretty good I think. The fin can Continue Reading

Mercury Redstone 1:52 Part 3

The Mercury Capsule with Escape Tower is assembled and glued. I still need to create a shock cord attachment, and if necessary add some weight to the nose. I am really happy with how this came out.

I decided to reprint the Capsule with the new printer. Not as obvious to tell from the photos, but in person there is quite a difference in quality. I’m glad I reprinted.

Mercury Redstone 1:52 Part 1

Posted In Mercury Redstone 1:52 Scale

I may have pushed the limits on my 3D printer with this one. After a number of failed attempts I was able to print the tower structure for a Mercury capsule. This is at 1:52 scale designed to fit in a Centuri ST-13 body tube (Estes BT-56). It is printed Continue Reading

Enerjet 1340 Fin Can 3D Print

Posted In 3D Printing, Model Rocket Building

JackHydrazine did a terrific job creating 3D files for the Enerjet 1340 fin can. The file can be found here: https://www.thingiverse.com/thing:3641770. I printed it overnight and it came out really well. I used PETG. It’s strong and can withstand higher temperatures like ABS and is not brittle like PLA, it Continue Reading

Saturn 1B 1:156 Part 3

Posted In Saturn 1B 1:156 Scale

To Engine Mount or Not to Engine Mount? That is the question. I have a dilemma. An 18mm BT-20 engine mount will not fit in the space left from the BT-4 tank tubes. I was planning on cutting out an 1/8 of an inch down the length of each BT-4 Continue Reading

Blast from the past, Estes renegade!

Here’s a blast from the past. An old favorite and workhorse, an Estes renegade kit #1271.  This launch was August of 1978 from my parents’ front yard. It flew on the mighty Estes D engine!
